What cloud resource should Sharon focus on after noticing a spike in application activity?

In the context of a spike in application activity, focusing on network bandwidth is essential because increased activity often results in a higher volume of data being transmitted and received over the network. Network bandwidth refers to the maximum rate of data transfer across a network path, and if applications are experiencing surges in usage, this can lead to congestion if the current bandwidth capacity is insufficient.

When applications suddenly generate more requests, especially in cloud environments where scalability is often tied to network performance, ensuring that there is enough bandwidth to handle the traffic is crucial for maintaining application performance, user experience, and operational efficiency. If the network bandwidth is not sufficient to accommodate the spike, it can slow down responses, lead to timeouts, or create bottlenecks, impacting the overall performance of the application.

While other resources like CPU and RAM are important for processing power and memory management, they might not directly address the immediate issue created by increased data demand on the network. Additionally, APIs facilitate communication between services but do not directly address the underlying concern of data transport capacity within the network. Therefore, focusing on network bandwidth addresses the core issue arising from a spike in application activity.
